Since this figure is communicating categories and not a gradient, a qualitative instead of a quantitative color scheme is probably easier to read. So e.g. in matplotlib dark2 instead of viridis. Sorry for the random nit-pick.

Would be nice to have somewhat more explicit description of the tasks it enables. Because I, as an astro PhD student, have yet to find a great usecase for these tools.

The image looks very much AI generated (hands, eyes, texture,...). Would be cool to communicate this, e.g. via the alt-text.

No, it is not! PLEASE just remove this AI nonsense. There are enough genuinely amazing images of the Helix nebula out there. No need to share this kind of slop.

Please! Provide a reference and best even a short explanation for these images.

Please give credit to the digital artist behind that image!

Interesting that for a story about joy, they chose a title image that shows BlueSky already being invaded by pseudo scientific AI slop.
